“AXIOM” is a Neon Outline text effect FontVibe AIで作成した文字エフェクト. 一本の青紫に光るネオン線だけで描いた中空のアウトライン大文字。内側は暗く、柔らかな光の輪と艶のある床への映り込み.

Pure neon outline letterforms — each letter defined only by its glowing stroke border, interior completely hollow and dark. The outline stroke glows with a continuous tube-light energy: bright white-hot center line along the stroke path, vivid neon glow zone expanding outward, soft wide halo bleeding into surrounding darkness. Glow is wider on the outside edge of the stroke than the inside, following real gas-tube light physics. Interior of each letter reads as deep void — no fill, no ambient light bleed inward. Stroke width is crisp and consistent, geometric precision. Slightly uneven brightness variation along the stroke path for organic gas-tube character. Choose neon color based on text meaning and mood: electric blue + deep violet for tech/cyber/cold words, neon pink + magenta for vibrant/pop/fun words, lime green + cyan for acid/gaming/matrix words, warm amber + orange for retro/diner/warm words, or multi-color with each letter a different hue for festive/creative content. Deep charcoal concrete wall texture — rough industrial surface with fine aggregate grain, subtle imperfections in the material. Cool blue-violet ambient scatter light from upper-left, soft directional depth across the wall surface. Faint haze of light diffusing in the air, micro-dust particles catching the illumination. Top-center: tiny label "NEON OUTLINE" at 35% canvas width, small refined caps, delicate presence. Center: "AXIOM" as massive dominant hollow neon outline letters at 65% canvas width, perfectly centered. Bottom-center: micro tagline "FONTVIBE.AI" at 20% canvas width, hairline weight. Vertical spacing ratio approximately 1:5:1.5. The wall is the stage — cold, urban, electric.
